Definitions

  • the present invention relates to a novel exosome and various uses thereof.
  • Extracellular vesicles are also referred to as cell membrane-derived vesicles, ectosomes, shedding vesicles, microparticles, exosomes and the like.
  • the exosome is an endoplasmic reticulum consisting of several tens to hundreds of nanometer-sized vesicles formed of a double phospholipid membrane having the same structure as a cell membrane, and contains protein, mRNA, miRNA, and the like, which are called exosome cargo.
  • Exosomal cargoes include a wide range of signaling factors, which are known to be cell type-specific and differently regulated according to the secreted cell environments.
  • Exosomes are intercellular signaling mediators secreted by cells, and it is known that various cellular signals transmitted through the exosome regulate cell behavior including activation, growth, migration, differentiation, dedifferentiation, apoptosis, and necrosis of target cells.
  • IBD Inflammatory bowel disease
  • Ulcerative colitis is characterized by inflammation of the colonic mucosa from the rectum to the proximal part of the large intestine, and involves mucus-stained bloody stools, diarrhea in several to dozens of times, and fever in severe cases.
  • Crohn's disease may occur in the entire gastrointestinal tract from the oral cavity to the anus, and usually cause abdominal pain, diarrhea, general weakness, weight loss or anal pain, and in severe cases, intestinal stenosis, perforation, abscess, fistula, etc., thus deteriorating the quality of life. In some cases, repeated surgery is required.
  • Enteritis is inflammation of the mesentery, which is classified into viral, bacterial, fungal, parasitic, addictive and historical records depending on the causes.
